LOCK.

Application filed August '7, 1915.

To all whom it may concern:

Be it known that I, EDWIN LEUSLEY, a citizen of the United States,residing at Huntsville, in the county of Randolph and State of Missouri,have invented new and useful Improvements in Locks, of which thefollowing is a specification.

This invention relates to improvements in looks, and has for one of itsobjects to provide a simple, inexpensive, durable and efficient rim ormortise look.

A further object of the invention is to provide a lock which shallembody a comparatively few number of parts that may be readily assembledwithout danger of derangement.

A further object of the invention is to provide a combination lock andlatch that eliminates the necessity of a locking bolt separate from thelatch.

A still further object of the invention is to provide a simple andeflicient means for securing and adjusting the knobs upon the knob shankor spindle, said means being operative from the exterior of the door towhich the lock is attached without necessitating the removal of the knobor key or any of the parts of the lock.

The preferred form of construction is illustrated by the accompanyingdrawings, wherein:

Figure 1 is a perspective view of a door having my improved lockarranged thereon, Fig. 2 is a horizontal sectional view taken in a linewith the center of the knob shank, the door being in its closedposition, Fig. 3 is an elevation of the lock, one of the side platesbeing removed, Fig. 4 is a similar view but showing the locking deviceas being actuated by the key, for locking the latch bolt, Fig. 5 is ahorizontal sectional view approximately on the line 5-5 of Fig. 3, theside plates of the lock being in position, and Fig. 6 is a perspectiveview of the locking device.

While, in the drawings, the improvement is illustrated as in the natureof a mortise lock, it is to be understood that the same may comprise arim lock if desired, and in the drawings the numeral 1 designates thelock casing having the usual removable side 2. 3 designates a latchbolt, 4 the latch throw, 5 the knob shank on the spindle which passeslaterally through the latch bolt, and 6 the latch bolt actuated spring.

All of the above parts may be of the ordinary construction, and thelatch bolt is, of course, reversible. However, the opposite ends of theknob shank 5 are provided with threaded openings 7 and the escutcheonplates 8 are formed with recessed bosses to receive the ends of the saidshank 5. The knobs for the shank 5 are indicated by the numerals 9, thesame having their sleeves provided with rectangular bores which enterthe knobs proper and terminating a slight but suitable distance awayfrom the outer faces of the knobs. Round openings 9' communicate withthe rectangular bores, the outer faces of the knobs being reamed, as at10, to receive the heads 11 of threaded The heads of the said membersare kerfed for the reception of an ordinary instrument, such as a screwdriver and the adjustable elements 12 are of a sufficient length to drawthe shank 5 longitudinally and to cause the ends of the sleeves of theknobs to be snugly received in the rings or depressions in the bosses inthe escutcheon plates. This arrangement. it will be noted, entirelydispenses with the employment of washers and with the necessity ofproviding the knob shank with trans verse threaded openings, and as theadjusting elements may be regulated from the exterior of the door, theconvenience of such an arrangement will, it is thought, be apparent.

Arranged within the casing 1 adjacent the key hole openings 13 is avertically disposed locking device, indicated by the numeral 1 Thisdevice 14 is of a width to be snugly received within the side walls ofthe casing and is retained in proper position through the medium of aspring presently to be referred to. The member 14: is provided with acentral channel 15 upon one of its faces, and the rear wall 16 of thechannel is formed with a pair of spaced curved depressions 17 and 18.The numeral 19 designates a flat spring which has its lower end disposedbetween two spaced studs 202O and its upper end provided with a curvedportion forming a lip 21. The lip 21 is adapted to be received in thedepression 17 when the locking device is in its negative position and tobe received within the depression 18 when the same is moved verticallyto bring the locking device in the path of contact directly to the rearof the tail piece 23 of the latch bolt 8. The

lower and what may be termed inner corner of the locking member lat isprovided with a substantially rectangular cut-away portion so that thestuds are connected to the permanent side of the casing, and the lowerstud 20 is positioned a suitable distance above the lower flange of thecasing so that the lower end of the spring may be bent between the saidflange and the said lower stud, thus insuring the proper retention ofthe spring within the casing. The spring, it will be noted, forces therear face of the locking member 1% against the rear Wall of the casingand the upper studkey hole opening 26 and the said face of the lockingmember below its lip is rounded inwardly, as indicated by the numeral27,- providing the lower portion thereof with an additional lip 28.locking device is in its lowered and what may be termed its inoperativeposition, is in the path of contact with the bit ofthekey when the sameis inserted through the key hole opening27 so that the locking devicewill be moved vertically and arrangeddirectly to the rear of the tailpiece 23 of the latch bolt 3, thus locking the latch bolt; The secondlip or contact member 28 is thus brought'into a position to be engagedby the bit of the key when the key is turned in an opposite or unlockingposition, so as.

to slide the locking device to its initial or idle position. WVhen thelocking device is in such last named position, the lip 21 of the spring19 will engage in the depression 17, but when the locking device ismoved to operative position, the said lip 21 will be :,in presence oftwo received within the depression 18, so that a the spring at all timesengages with-the memberl-ftand effectively sustains the same in properposition in the lock casing.

While I have illustrated and describeda 1 The lip 25, when thesatisfactory embodiment of the improvement as it now appears to me, itis to be understood 'thatthe same is susceptible to changes in the minordetails of construcspring for the latch bolt,-of a -,verticallymovable'loosely positioned locking member in the casing disposednormally. below the tail-pieces of the latch bolt, said locking.
